CRITERIA FOR MATCHING SOIL RATINGS WITH PESTICIDE INDICES


Pesticides with less potential to adversely affect water quality can be selected by matching the soil ratings and
pesticides using the following criteria:

PROCEDURE FOR SELECTING PESTICIDES
TO REDUCE ADVERSE WATER QUALITY
IMPACTS

A "Pesticide Selection Worksheet" is provided as a
convenient way to organize the information needed
to select pesticides to avoid water pollution by
pesticides in a particular production or management
unit. Instructions for using the worksheet are
outlined below. The function of the worksheet is to
match the soil leach and runoff ratings at the
application site with the pesticide RLPI (leaching)
and RRPI (runoff) indices and toxicity values given
in Table 1.


This will indicate the relative potential for pesticides
to leach or run off from a particular site and
consider the toxicity of the pesticides to humans or
aquatic life if the pesticides leach into groundwater
or if runoff enters surface impoundments or
streams. The last two columns are for recording the
peach grower's choices and reasons for selecting
particular products.

Our intent is to provide a decision support tool for
the peach grower. The grower is responsible for
making the final choice. The completed worksheet
can serve as a permanent record of the selection
process used and decision made by the grower.

USING THE WORKSHEET


1. TARGET PEST: Correct identification of the
pests that need to be controlled is essential! Check
with knowledgeable experts and utilize competent
diagnostic laboratories so that a proper diagnosis
can be made. Misdiagnosis results in the wasteful
use of unnecessary pesticides and needless increases
in production costs. List confirmed pests in column
1 of the Pesticide Selection Worksheet.


2. RECOMMENDED PESTICIDES: Use the
current IFAS Pest Control Guides, or other
appropriate information sources to identify the
pesticides that control the pests of concern. List
these pesticides in column 2 of the Pesticide
Selection Worksheet.


3. PESTICIDE PROPERTIES: For each pesticide
listed in column 2 on the Pesticide Selection
Worksheet, copy the numeric value for K, RLPI,
RRPI, HALEQ, and Aquatic Toxicity from Table 1
into columns 3, 4, 5, 6, and 7 of the Pesticide
Selection Worksheet.


4. SOIL PROPERTIES: Consult the County Soil
Survey Report soil map sheets to locate your
production orchards and to identify the soils that
occur in these orchards. Use the Soil Science Fact
Sheet entitled "[Your County]:Soil Ratings for
Selecting Pesticides" (available from your county
Cooperative Extension Office) to determine the
leaching and surface runoff rating of the soils in
your orchards. As you determine the soil leach
rating and the soil runoff rating for each soil in each
orchard, list the soil name, soil leach rating, and soil
runoff rating in columns 8, 9, and 10, respectively,
of the Pesticide Selection Worksheet.


5. SELECTION OF PESTICIDES: Using infor-
mation that you have compiled on the Pesticide
Selection Worksheet, select appropriate pesticides
using the selection criteria on page 4 to match soil
and pesticide properties. The selection made can
be recorded in column 11 and notes relating to the
selection can be recorded in column 12.


Notes:
1. If the pesticide product selected is a formulated
mixture or a tank mix, each active ingredient must
be considered. The most restrictive pesticide in the
mixture will determine the choice. Trade names in
Table 1 followed by (M) are formulated mixtures.

2. Sometimes there may not be a clear choice from
among the alternative chemicals available to control
a particular pest. In these cases, first order
screening using the RLPI or RRPI only can suffice.

3. Depth to groundwater and local geohydrology
may influence your final selection. Shallow
groundwater is more vulnerable to contamination.
Deep water tables with intervening impermeable
geologic layers are much less vulnerable.

4. Distance to surface water bodies may also
influence your final selection. Surface waters
adjacent to or near the pesticide application site are
more vulnerable to contamination than those further
away. If surface runoff from the application site
usually infiltrates into the soil off site before
reaching a surface water body, then the HALEQ
should be considered as the secondary screening
index.
